<\/p>\n, marks a big change for the iconic model. Big, that is, in terms of size. While it rides on a thoroughly reworked version of the current 996\/997 platform, it will be visibly larger. Set to be unveiled this fall at the Frankfurt auto show and go on sale as a 2012 model, the 991 gets a longer wheelbase to accommodate its airier interior. The cabin\u2019s materials and console layout will be nicer, too, with more than a passing resemblance to the Panamera\u2019s.<\/p>\n
Porsche started work on the 991 under former R&D chief Wolfgang D\u00fcrheimer, now at Bentley and Bugatti, and the former CEO, Wendelin Wiedeking. After Volks\u00adwagen assumed control of \u2009Porsche, styling changes were reportedly incorporated at the \u201crequest\u201d of\u2009 Ferdinand Pi\u00ebch.<\/p>\n
Given the next 911\u2019s longer wheelbase, we expect a more supple ride without a corresponding sacrifice in dynamic competence. Like every 911 before, the new model will remain rear-engined. Rear-wheel drive will, of course, be standard, and all-wheel drive\u2014an option since the 1989 Carrera 4\u2014will be available. The standard engine will be the naturally aspirated flat-six, likely in two displacements, as is currently the case. We don\u2019t expect huge power increases, but Porsche will employ electric-assist steering to aid efficiency and some weight-saving measures such as more aluminum body panels.<\/p>\n
The Turbo will remain at the top of the portfolio, and there are even plans for a hybrid version. More unexpectedly, Porsche might also offer a turbocharged flat-four. Such a model would be easy to justify historically\u2014the 356 was a four, as was the 912. But a turbocharged four could get awfully close to the naturally aspirated six and dilute the \u201cTurbo\u201d moniker, which is still associated with the top-hole 911s.<\/p>\n
Predictably, there will be a coupe and a convertible body as well as numerous variations, such as future GT2 and GT3 models. Their successive launches mean that the current 997 and the new 991 will be built alongside each other for a while.<\/p>\n
Porsche knows the Cayman\u2019s mid-engine arrangement is dynamically superior to the 911\u2019s, but the latter\u2019s rear-engine \u00adlayout enables usable rear seats. Plus, it helps to create those classic proportions. <\/p>\n
